A liquid crystal display panel. A photo spacer in the prior art is replaced by an oriented carbon nanotube array. In the manufacturing method for a liquid crystal display panel, a spacer (30) formed by the oriented carbon nanotube array is obtained by growing the oriented carbon nanotubes in the spacer (30) of the substrate on one side of the liquid crystal display panel. Performance and the service life of the liquid crystal display panel are remarkably improved by making use of excellent mechanical performance and extremely-high stability of the oriented carbon nanotubes.
